Sempervivum arachnoideum ‘Cobweb Hens and Chicks’ are low-growing, clump-forming succulents with green rosettes covered in a white, hairy webbing. The plant turns purplish brown in full sun and when exposed to the cold weather. Like most sempervivums, these plants grow in clumps and spread by producing offsets and pups.
At first glance, the plant looks like it is covered in spider webs. This is actually an adaptation by the plant to protect against the harsh rays of the desert sun. These make excellent ground covers as well as container plants due to their easy-going, adaptable nature
